As you can see from the sentence before the one you quoted, I didn't forget about it.

I agree there's a lot of complexity there. But it's still a relatively small slice of the population. A friend is a farmer; she's just carrying ahead farming. Compared with urban life, she's been "socially distancing" for years. For the more dense parts of the chain, we need to take other infection-prevention measures. But food production is already pretty good at keeping things clean, and the rest we can work on.
